Based on Kohn, below, there is some reason to believe that the Texas deaths were from the St. Louis Encephalitis Outbreak in the Lower Rio Grande Valley, TX, in 1954.
Kohn: “Houston Encephalitis Epidemic of 1964 — Largest of several St. Louis encephalitis (SLE) flare-ups that broke out across the United States in the summer of 1964. The Houston epidemic’s extent exceeded that of the 1954 Rio Grande Valley, Texas, and 1962 Tampa Bay, Florida, outbreaks…” (p. 143)
